Major Balthazar parts are:

Power Controller and battery

These supply power to the rest of the system, particularly the System on a Module, USB Hub and Display subsytem. It also manages battery.

It should be capable enough to run some USB connected hardware.

See more: Power Supply

System on a Module (SoM)

This is the main system board, the computer. Boards from different makers should be supported.

Minimum of ports is required for wider compaitibility. These are: Power, USB and HDMI.

See more: System on a Module

I/O USB hub

IO-board basically means connectivity with peripheral devices. These can be seen as on-board and out-board. On-board devices include: keyboard + trackpad, webcam and optional audio-card. USB is the usual solution for this.

For more see our I/O USB page.

Case

Initial casing is meant to be made of a recyclable vegetable oil based plastic. Also the idea of a modular design gave us even more sustainable materials to look at - pressed used clothes in resin, cans recycled pressed aluminium and even resin-ed wood saw.

Here are elements we have been working with so far and slowly shaping the final design and a certain materials together.

On our Github page you can look into the .stl files too.
